Nintendo has announced the next Splatfest, coming to Splatoon 2 next month. This time, Nintendo has partnered with Nickelodeon to bring a Teenage Mutant Ninja Turtles theme to the game.

It also heralds the first tournament-style Splatfest, with two rounds of battles, followed by a showdown to determine the ultimate fan-favorite turtle.

Voting starts tomorrow, April 27, through the in-game Inkopolis Square. The first of the three in-game Splatfest tournaments will take place on May 4-5, pitting Raph against Leo. Mikey will face Donnie from May 11-12, with the two finalists competing on May 18-19. Here’s the full schedule:

Round 1: Raph vs. Leo
May 4 (Friday), 9 p.m. PT – May 5 (Saturday), 9 p.m. PT

Round 2: Mikey vs. Donnie
May 11 (Friday), 9 p.m. PT – May 12 (Saturday), 9 p.m. PT

May 18 (Friday) 9 p.m. PT – May 19 (Saturday), 9 p.m. PT
